No the ST7735 driver is an SPI device only. The more expensive of the two form OP's post is identical to one from Adafruit to the SD card and footprint for the 8 pin eprom on the back side. the real difference is the $15.00 price difference.

// Option 2: must use the hardware SPI pins// (for UNO thats sclk = 13 and sid = 11) and pin 10 must be// an output. This is much faster - also required if you want// to use the microSD card (see the image drawing example)//Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, rst);

The answer to the overlaid printing is to first print a blank line over the text you are refreshing.Glcd.print(" "); or something similar. I'm not at home now so I can't share the example code. If you need it I'll be happy to post it later today.

@Docedison - Thanks Bob I would quite like to see the code if you don't mind.

Will the above work or do I have to change the #define pins, or does something in the library set it up?
